reviews: Nice parking antenna, but not that reliable.\r\n\r\nWhen parking against solid objects, that\'s ok, but against a car, or in a angle you\'ll hit before it starts to beep continuously.\r\n\r\nBut it\'s fully hidden and there\'s no extra holes in the vehicle.\r\n\r\nIf you don\'t\' want to see the sensor, buy it, other wise prefer the ones that has 4 or 6 sensors
